Need an extra motherboard USB header

I need to add an additional USB header for my Gigabyte motherboard, the 2 headers on the motherboard are dedicated to running the 4 USB ports on the front panel.However I am adding an additional device to the front panel that also requires a USB header, so an obvious solution would be a splitter of some kind that would allow one of the headers to pull double duty for the front panel USB ports as well as facilitating the new device. Anyone ever hear of a Y splitter or some other solution that can make this work?,I could always just unplug one of the headers and go with just 2 USB ports on the front but I would rather not make any compromises.
